In order to qualify for SureStart PLUS extended warranty coverage, the roof system must be installed by a contractor with anup-to-date ShingleMaster™ or SELECT ShingleMaster™ credential, and must meet the Integrity Roof System™ requirements. ShingleMasters can sell 3-STAR and 4-STAR Coverage – SELECT ShingleMasters can sell all three levels of coverage. SureStart PLUS extends the standard SureStart protection provided by the warranty in force on the date the shingles were purchased.
